Definitions
- This invention relates to an on screen interactive electronic program guide (EPG) with advertisements and, more particularly, to coordinating the display of video clips with static advertisements in an on screen EPG.
- EPG electronic program guide
- These advertisements are typically transmitted with the EPG data to user terminals, e.g., television receivers, and displayed on the monitor at the terminal simultaneously with television program listings.
- An effective advertisement must attract the attention of the television viewer during the period of time that the on screen EPG is displayed.. Live video action is a powerful attention getter. Thus, it would be highly desirable to incorporate live video advertisements into an on screen EPG.
- EPG data, static advertising messages, and video clips relating to the advertising messages are all transmitted to a plurality of user terminals such as television receivers.
- the video clips are tagged with unique identifiers, e.g., identification numbers or words.
- the static advertising messages also include the identifiers relating to the respective advertising messages.
- a feature of the invention is to transmit the video clips in real time so they do not have to be stored at the user terminals.
- the video clips are transmitted continuously on digital channels; the identifier of each video clip or packet containing video clip information is compared with the identifier of the advertising message scheduled to be displayed, and the video clip or packet containing video clip information is selectively grabbed when the identifiers match.
- Another feature of the invention is to transmit the television signals, the EPG data, the advertising messages, and the video clips as an RF signal or group of signals from a single broadcast or cablecast source.
- Another feature of the invention is to couple an EPG data base server to a video clip server to append unique identifiers to the video clips and to append the identifiers to the respective static advertising messages prior to transmission to user terminals where the static advertising messages and video clips will be displayed in an on screen EPG .
- FIG. 1 is a schematic block diagram of an EPG server and a video clip server connected to a plurality of cable headends that transmit television signals;
- FIG. 2 is a schematic block diagram of one of the cable headends represented in FIG. 1 ;
- FIG. 3 is a schematic block diagram of one of a plurality of viewer terminals that receive television signals from one of the headends represented in FIG. 2 or another type of television signal transmission source such as over the air or satellite; and
- FIG. 4 is a diagram of an on screen EPG displayed on a in monitor at a viewer terminal in accordance with the invention.
- the invention is used in conjunction with the interactive electronic program guide (EPG) described in Application No. 08/475,395 filed June 7, 1995 (our Docket No. 27971/LTR/E 190) and Application No. 09/120,488 filed July 21, 1998 (our Docket No. 32714/LTR E190), the disclosures of which are incorporated fully herein by reference.
- EPG interactive electronic program guide
- a national video clip server 10 stores video clips to be displayed on the screens of the television monitors of all the viewer terminals that support this interactive EPG.
- the video clips are typically short, e.g. 10 to 30 seconds, motion picture scenes with or without sound.
- a national EPG data base server 12 stores program schedule data (including static text based or graphic product, service, or television program advertising messages) to be displayed on the screens of the television monitors of all the viewer terminals that support this EPG.
- the content of the video clips relate to and further enhance the respective advertising messages, and thus focus the viewer's attention on the subject of the advertising messages.
- Servers 10 and 12 are connected by a cable, telephone, or wireless transmission link to all the head ends (designated 14) of the cable or broadcast systems that distribute the EPG data with a television signal to transmit EPG data and video clips thereto.
- Head ends 14 have unique addresses so data can be targeted to a particular head end.
- Server 12 selectively addresses each of head ends 14 to furnish EPG data customized to the program lineup and advertising messages for the television viewers served by that particular head end.
- server 12 controls the distribution of video clips by server 10, so server 10 also selectively addresses each of head ends 14 to furnish the video clips relating to the advertising messages transmitted to that particular head end from server 12.
- the video clips are tagged with unique identifiers or words. The identifier of each video clip is also stored in the EPG data base with the related static advertising message so the video clip can be retrieved later for display at the same time as the static advertising message.
- FIG. 2 illustrates the apparatus at one of head ends 14 for carrying out the invention.
- a head end computer 18 is programmed to coordinate the transmission of video clips and EPG data with television programs over a cable feed 20.
- An EPG data base receiver 22 selectively grabs the EPG data addressed to the particular head end. Under the control of computer 18 this EPG data is stored in an EPG data base memory 24 and updated one or more times each day.
- a TV signal source 26 is connected by an EPG data inserter 28 to a multiplexer (MUX) 30 for transmission over cable feed 20.
- MUX 30 could be connected to a broadcast antenna, satellite uplink input, etc., depending upon the form of distribution of the television signals.
- Computer 18 feeds the EPG data stored in memory 24 to inserter 28 for transmission to the viewer terminals with the television signal.
- Television signals designated 32, from other sources, i.e. stations, are directly connected to MUX 30.
- a video clip receiver 34 selectively grabs the video clips addressed to the particular head end. Under the control of computer 18, these video clips are stored on video clip storage disks 36 for use by a video clip server 38.
- Server 38 furnishes video clips to MUX 30 for transmission over cable feed 20.
- the video clips are transmitted and stored in compressed digital form, such as
- MPEG at national server 10 and at head ends 14. They are also transmitted and stored in reduced size, i.e., one ninth or one quarter of the full screen size. These measures reduce the bandwidth requirements for transmitting the video clips.
- the television signals could be transmitted in analog or digital form.
- the implementation of inserter 28 and MUX 30 depends upon the form of the signals, i.e., analog or digital. For example, if the television signals are in digital form, MUX 30 could combine the television signals and the video clips into a single digital stream or several digital streams modulated at different frequencies for transmission together over cable feed 20. If the television signals are in analog form, inserter 28 would be a VBI encoder and MUX 30 would include frequency and amplitude modulators and frequency up- converters to frequency divide the television signals to separate channels.
- the video clips are preferably inserted by MUX 30 on one or more digital channels for transmission over cable feed 20 with the digital or analog television signals.
- the video clips are preferably transmitted continuously, i.e., repeatedly, in real time on a plurality of digital channels.
- a video clip is always available in real time for display when the corresponding static advertising message is scheduled to be displayed.
- the channels are digital in the sense that the video clips are carried in a common stream of video data in digital, preferably compressed (MPEG) form in separately tagged packets modulated on one or more carrier frequencies; the packets of each video clip are interleaved with the packets of the other video clips in time division fashion such that the channel carrying the selected video clip can be recovered in real time.
- MPEG preferably compressed
- FIG. 3 illustrates the apparatus at one of the viewer terminals for carrying out the invention.
- the viewer terminals could comprise one or more of a television receiver, satellite receiver, VCR, a cable converter, etc. Only the portion of the viewer terminal applicable to the invention is shown.
- the viewer end of cable feed 20 is connected to a channel selector 40 and a video clip selector 42.
- Channel selector 40 is coupled by an EPG data extractor 44 to one input of a switch 46.
- the output of switch 46 is connected to a television monitor 48.
- a microprocessor 50 controls the disclosed apparatus as well as the remainder of the viewer terminal.
- channel selector 40 comprises a conventional frequency downconverter, channel frequency tuner, and frequency/amplitude demodulator and data extractor 44 comprises a VBI decoder. Responsive to a viewer input or predetermined time schedule, microprocessor 50 sets channel selector 40 to the desired channel for television reception and/or downloading of EPG data.
- EPG data is embedded in the television signal, it is coupled by data extractor 44 to microprocessor 50, which stores the EPG data in an EPG RAM 52 for display on monitor 48 in the EPG mode of operation of the viewer terminal.
- microprocessor 50 retrieves EPG data from RAM 52 and directs the retrieved EPG data to a video processor 54 in which program listings are composed in a bit map corresponding to the pixels on the screen of monitor 48.
- Channel selector 40 and video processor 54 are coupled to a conventional PIP chip 56.
- PIP chip 56 is connected to the other input of switch 46.
- switch 46 Under the control of microprocessor 50, switch 46 is placed either in a television viewing mode or an electronic program guide (EPG) mode. In the television viewing mode switch 46 connects channel selector 40 to monitor 48 to display a full screen image of the program on the channel to which selector 40 is set.
- EPG electronic program guide
- FIG. 4 illustrates a typical display 58 on the screen of monitor 48.
- Television program listings occupy an area 62 on the screen.
- a PIP window occupies an area 64 on the screen.
- the television program on the channel to which selector 40 is set is displayed in the PIP window in real time and the sound thereof is reproduced by monitor 48.
- selector 40 is reset to the corresponding channel so the program is displayed in the PIP window.
- the setting of selector 40 does not change as different program listings in area 62 are highlighted by the cursor, so the program displayed in the PIP window remains unchanged.
- a static advertising message occupies an ad window area 66 on the screen.
- Another static advertising message could occupy a program listing area 68 as a "virtual channel" within area 62, instead of one of the television program listings.
- a video clip is displayed in relatively low resolution reduced size, i.e., not full screen, in an ad window area 70 on the screen as further described below. This low resolution motion picture image requires less bandwidth to transmit and store than a full screen image.
- Microprocessor 50 ascertains the identifier of the static advertising message displayed in area 66 or 68 and sends the identifier to video clip selector 42 for comparison with the identifiers of the video clips in the incoming data stream. If there is more than one carrier frequency, selector 42 switches to the correct carrier frequency before comparing the identifiers in the data stream.
- the video clip is coupled to video processor 54 to be included in the bit map and displayed in area 70, as illustrated in FIG. 4.
- video processor 54 As described in Application No. 09/120,488, it is desirable to rotate the static advertising messages based on a predetermined plan.
- a new static advertising message is displayed in the EPG, a new video clip is also recovered from the data stream by microprocessor 50 and displayed in area 70. If there is no video clip available, a static message is displayed in area 70.
- the static advertising messages stored in RAM 52 are embellished by the video clips sent to the viewer from the head end.
- the video clips could be transmitted to the viewer terminals by a different communications link, e.g., the Internet, a separate data channel, or a direct telephone connection.
- a different communications link e.g., the Internet, a separate data channel, or a direct telephone connection.
- an Internet link is used to transmit the video clips, it is possible to selectively transmit only the desired video clip from the video clip server at the Internet site on command from head end computer 18 when the corresponding static advertising message is to be displayed, rather than continuously transmitting all the video clips, to the viewer terminals.
